Supraventricular tachycardia (SVT) poses a clinical challenge during pregnancy, particularly if refractory to antiarrhythmic medications. Performing catheter ablation during pregnancy necessitates careful risk benefit analysis for both the mother and fetus, especially with left-sided ablations that may require post-procedural systemic anticoagulation. We describe a pregnant woman with refractory atrial tachycardia (AT) which failed a multi-antiarrhythmic drug regimen and ultimately developed abruptio placentae, requiring a carefully staged ablation approach for definitive treatment.
